Subject: nice position

Author: Will Singleton

Sometimes Crafty gives me a headache.  I was sitting there, minding my own
business, when all of a sudden pow!  and Crafty wins another one.  Must be
something to this smp business.

Anyway, on ICC Crafty runs on a 2x 2.8ghz xeon.  It found Rxg6 in about a
minute, if you count my thinking time plus its thinking time (assuming it
pondered correctly, which it probably did).  If I run the same position on my p4
2.8ghz, it takes Crafty 4:44 to find the move.  I suppose the hash could affect
things, but that's still quite a speedup.

Here's the position.  Finding Rxg6 probably depends in large part on
king-safety, since Amateur likes it fairly quickly (p4 2.8ghz):
